The group of undead could have been a threat. Could be the operative word. If these undead had ambushed one of the guard groups or the younger adventurer groups, then sure, they would have needed to put up a major fight. However, the party was barely worried since Alice had already made a move after the false wall had been pointed out.
A single change in tune shaped the light balls Walker left around them in to spears of light. They shot through the air purifying the undead mana and destroying the skeletons who had been using earth magic to hide as an ambush. It also caused a small burst of light showing off even more of the passageways ahead.
It was a crossroad leading toward three rooms. One the group could see led to a deeper floor and two that appeared to be closed off storage rooms. The stone doors weren't carved or locked in any impressive ways. Walker even pointed out the places that someone could grip them to easily channel in earth mana.
